Why can't pearl necklaces be washed by ultrasonic?

The working principle of ultrasonic cleaning machine is to use cleaning liquid as medium and emit low-frequency wavelength, so as to wash away the dirt on gemstones. However, jewelry cleaning solution contains chemical components, and pearls are easily corroded when they come into contact with chemical components. In addition, the hardness of pearls is not high, and the vibration of ultrasonic cleaning machine and the chemical reaction of cleaning solution are devastating to pearls.

Selection skills of pearl necklace

Generally speaking, pearls with no light or less light lack aesthetic feeling, so the quality is poor. According to the luster of pearls, we can divide them into four grades, that is, extremely strong, strong, medium and weak, that is, four grades A, B, C and D in the picture below. Among them, Grade A, the reflected light is particularly bright, sharp and uniform, and the image is clear, which is the top grade among pearls. Class B, the reflected light is bright, and the object image can be seen on the standard surface, and the quality is second only to Class A. Class C, the reflected light is not bright, and the object can be seen on the surface, but the image is blurred and the quality is slightly poor. Grade d, the reflected light is almost diffuse, the surface gloss is dim, and there is almost no image, so it is a relatively poor pearl product.
